How much force is needed to accelerate a 25kg bowling ball at 2m/s². 

• 50 N

• 5 N

• 12.5 N

• 100 N

If a 2kg bird is pushed by the wind with a force of 2N, how fast does the bird accelerate?

• 1 m

• 2 m/s^2

• 4 m/s^2

• 1m/s^2

 

Newton's law of motion describes the relationship of force, mass, and acceleration. Write the equation.

• m=F*a

• F=m*a

• a= F/m

• All of the above

What is the acceleration of a 50 kg object pushed with a force of 500 newtons?

• 100 m/s^2

• 0.1 m/s^2

• 10 m/s^2

• 25 m/s^2

A force of 250 N is applied to an object that accelerates at a rate of 5 m/sec².  What is the mass of the object?

• 100 kg

• 0.02 kg

• 50 kg

• 5 kg

What is the unit for FORCE? 

• N

• kg

• m/s^2

Acceleration is measured in

• N

• kg

• m/s^2

• m/s

What is the force of an object with a mass of 30 kg and an acceleration of 10 m/s2? 

• 300 N
